Overall singles sales for the year in the U.K. came in at 182.2 million, just shy of a record of 186.6 million set in 2012, according to data from the Official Charts Company and British recorded music trade body BPI.

Total trade music revenue in Britain again topped $1.66 billion (£1 billion), they said without providing further details.

Album sales were worth £772 million in 2013. CD sales of 60.6 million were down almost 13% on 2012's total, but despite the impression the format is dead, CDs still account for almost two thirds of all albums sold in the UK.

Streaming revenue broke the £100 million ($166 million) barrier in 2013 for the first, with the estimated $170 million accounting for 10% of the overall value of U.K. recorded music sales, the data trackers said.

"The success of digital music in 2013 surpassed all previous records – we celebrated the one billionth track download, counted four million-selling digital singles, and streamed more than 7 billion songs," said BPI CEO Geoff Taylor. "As digital music moves into the streaming era, the prospects for future growth in the U.K. music market look strong."

"Blurred Lines" sold more than 1.47 million copies since it debuted at No. 1 in Britain in June. The song spent five weeks in the top spot, making it the longest running No. 1 hit of 2013.

"Get Lucky," which was the French dance duo’s first-ever U.K. chart topper, ended the year with a sales tally of more then 1.3 million copies.

Williams said about the two top singles of the year that he was involved in: "I'm humbled by all of the love the U.K. fans have shown. But, when you are working with incredible talent like The Robots and Robin, great things are bound to happen." His current single, "Happy," became Britain's final number 1 of 2013.

Two other singles released during the year topped the 1 million sales mark in Britain.

Swedish DJ Avicii claimed the third biggest selling single of 2013 with "Wake Me Up," which has sold 1.18 million copies, while Britain's own Passenger, aka Mike Rosenberg, sold more than 1.03 million copies of "Let Her Go," which peaked at No. 2 in the charts.

Naughty Boy’s "La La La" sold more than 941,000 copies since it was released in May to round out the top five singles of the year.

The top 10 biggest singles of 2013 in Britain each sold over 710,000 copies. U.K. artists accounted for 37.5% of all tracks in the Official Top 40, down from 45% in 2012.

Beyond Passenger, Bastille are the highest-ranked British group with their hit "Pompeii" coming in 11th for the year, while Ellie Goulding is the best-selling British female artist of 2013 with "Burn," which came in 15th for the year.

The biggest-selling album overall in the U.K. was compilation Now That's What I Call Music 86, which sold 1.1 million copies. As reported earlier in the week, One Direction's "Midnight Memories" was the biggest-selling artist album of the year in Britain with 685,000 copies sold by year's end.

That makes it nine years in a row that a U.K. artist has had the top seller in the country. The others were Emeli Sande with "Our Version Of Events" in 2012, Adele's "21" in 2011, Take That's "Progress," Susan Boyle's "I Dreamed A Dream," Duffy's "Rockferry," Amy Winehouse's "Back to Black" in 2007, Snow Patrol's "Eyes Open" in 2006 and James Blunt's "Back to Bedlam" in 2005.

"The British public's affinity for British music is alive and kicking," said BPI chairman Tony Wadsworth. "For an impressive ninth year in a row, a U.K. artist signed, developed and supported by a British record label has claimed the best-selling artist album on home turf."

Other top 10 albums last year came from former Take That stars Robbie Williams and Gary Barlow, as well as Rod Stewart.
